3.5” Sport ST3 Suspension System – 35-37” Tires

.

At home on black diamond trails or city streets, the 3.5” Sport ST3 Suspension System builds on the 2.5” Sport ST2 by replacing the Sport Flexarm Front Lower Preset Control Arms with Front Control Arm Sport Brackets as well as adding an HD Forged Front Track Bar Bracket and a set of Front Brake Line Anchors.

.

Although this kit clears the same size tires as the 2.5” Sport ST2, the additional components increase ground clearance without compromising on- and off-road prowess. No alignment is needed thanks to the Front Control Arm Sport Brackets, which optimize correct caster angle and restores factory geometry for 2.5-4.5” lift, while the HD Forged Front Track Bar Bracket corrects steering geometry to eliminate bump steer and other steering issues for 2.5-3.5” lift kits.
